'SPEGIFICATION forming part of Letters Patent No. 689,567, datedDecember 24, 1901.

Application filed September 11, 1900. Serial No. 29,711. (No model.)

To all whom, it may concern:

Be it known that I, JOHN A. SE OOR, a citi- I 'zen of the United States,residing in the borough of Brooklyn, in the city of New York, in theState of New York, have invented certain new and useful Improvements inEngine- Frames; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, making a part of this specification, in which-Figure 1 is an end elevation of an engineframe made according to myinvention. Fig. 2 is a side elevation of the same. Fig. 3 is a verticallongitudinal sectional view of the same, taken in the line at x of Fig.2. Fig. 4 is aplan view of the same. Fig. 5 is a detail view, on alarger scale, still further illustrating my said invention.

This invention relates to the frames of vertical engines, using the termframe as including the cylinder as a part of the frame. It is applicableto motors of this type,whether operated by steam, explosive fluids,compressed air, or other means. Its object is to simplify the structureof such motors, per mit their more economical manufacture, provide forgreatly-increased firmness and stability of the motor-cylinder in itsrelations to other parts of the frame, and to promote the greaterdurability and working life 'of the engine under the many and severevicissitudes of use under ordinary conditions of Wear and tear.

To this end the invention comprises certain new and useful combinationsof parts hereinafter fully set forth and specified.

A is a horizontal bed-plate which is hollowed out underneath, as moreclearly shown in the sectional view, Fig. 3, to provide room for theends of the straining-braces and nuts, herein presently described. Onthis bed-plate may be provided the bearings, which are shown at a, forthe crank-shaft of the motor.

B is the cylinder of the motor, which may be of any desired size, shape,or proportion, according to the variety to which the motor, whetherexplosive, steam, or other, may belong. The cylinder at its lower end ispro vided with outwardly extended lugs b or equivalent projections. Inthese are provided ends.

vertical sockets c, which are coincident with vertical sockets d,hereinafter described, of the bed-plate below.

O represents standards which rise from the bed-plate and upon which thecylinder is supported. The upper and lower ends, respectively, of thestandards are shouldered, as shown at e and t' in Figs. 3 and 5, theupper end portions g of the standards having the thus relatively-reduceddiameters being inserted into the sockets c of the cylinder-lugs I),while the correspondingly-reduced lower end portions h of the standardsare inserted in the sockets d of the bed-plate. The standards aresupported by their shoulders t', bearing upon the bed-plate, while thecylinder is supported upon the shoulders e at the upper parts of thestandards. Any desired number of standards may be employed; butordinarily four is sufficient for purposes of utility, and such numberis ordinarily to be preferred. The extremities of the standards may whendesired be extended beyond the respective sockets in which they areplaced and may be threaded to receive nuts a b, as shown in Figs. 3 and5. In each of the lugs 12 is an oblique internally-screw-threaded boreIt. At proper points in the bed-plate below are non-threaded bores m,the axis of each of which is coincident with the axis of the threadedbore It in the cylinder-lug above it and with which, as presently hereinexplained, it is designed to cooperate. The surface surrounding thelower end of each bore m in the bed-plate should be made flat, orapproximately so, in a plane at right angles to the axes of the saidbore and the corresponding threaded bore k of the cylinder-lug above toprovide a nut-seat n, for a purpose herein presently explained.

At D are oblique tension-braces, each of which is screw-threaded at itstwo opposite The upper end of each brace is firmly screwed into one ofthe internally-threaded bores 7c of the cylinder-lugs I), while itslower end is passed through the coincident bore m below in thebed-plate. The screw-threaded lower extremity of each tension-brace isextended below the bottom of the bore m,

through which it is passed, and has upon it a nut 1", which rests snuglyupon the seat n,

provided by the surface around the lower end of the bore, as hereinpresently explained. The cylinder being duly placed upon the standardand the tension-braces being put in position as just described, the nuts1' are turned to tighten upon their seats n, and consequently draw uponthe tension-braces D, longitudinally straining the same to tighten thecylinder downward upon the standards with a compressive strain upon thelatter, which said compressive strain resists the tensile strain exertedupon the tension-braces. The tension-braces thus not only tend to resistany lateral or horizontal thrust or displacement of the cylinder ordeviation of the latter from its perpendicular position, but exert apositive and continuous strain upon the cylinder to hold the latterfirmly upon the standards, thereby bringing the several parts into suchrelations of tensional and resisting pressure that each supports theother and greatly increased stability is afforded to the whole. At thesame time the number of nuts and other devices as compared with thoseessential in ordinary engine-frames are greatly reduced in number andthe expenses of manufacture are proportionately diminished, while forthe reasons above indicated a much greater strength of frame inproportion to the weight of materials used therein is secured.

lVhat I claim as my invention is- An engine-frame comprising incombination a bed-plate having vertical sockets and oblique bores, acylinder having vertical sockets and outwardly-extended lugs in whichare oblique screw-threaded bores, vertical standards which have theirshouldered upper and lower ends inserted in and shouldered on theshoulders of the vertical sockets of the cylinder and bed-platerespectively, oblique tension-braces which are screw-threaded at theiropposite ends, each with its upper end screwed into a threaded obliquebore of a cylinder-lug and with its lower end passed through andprojected below a correspondingly-oblique bore in the bed-plate, andnuts upon the lower extremities of the strainingbraces and standards totighten the same and compress the cylinder upon the standards,substantially as herein set forth.
